Philadelphia Flyers forward Oskar Lindblom, St. Louis Blues defenseman Jay Bouwmeester, and Ottawa Senators forward Bobby Ryan are among the 31 finalists for the Bill Masterton Memorial Trophy, the Professional Hockey Writers' Association announced Tuesday.

Lindblom was diagnosed with Ewing's sarcoma - a type of cancer that occurs in bones or soft tissue - in December. The 23-year-old missed the rest of the regular season. The Flyers rallied around him, and their fans gave the blue-liner a standing ovation when he attended a game in January. As of late April, Lindblom was scheduled to undergo his final cancer treatments.

Bouwmeester suffered a cardiac episode during a game between the Blues and Anaheim Ducks, a February contest that was postponed as a result. The 36-year-old rearguard later underwent surgery to implant a defibrillator, which restored his heart's normal rhythm. He also missed the remainder of the regular season.

Ryan took a leave from the Senators to enter the NHL and NHLPA's player assistance program in November. The winger later revealed he had a panic attack and was battling alcohol abuse. Ryan, who turned 33 in March, returned from the program in February and notched four goals in eight games, including a hat trick against the Vancouver Canucks.

The NHL awards the Masterton Trophy to the player "who best exemplifies the qualities of perseverance, sportsmanship, and dedication to hockey." The PHWA annually votes on the award and narrows down the list to three finalists before the winner is determined.

Here's the complete list of 2019-20 nominees:
